The Neotropical Companion by John Kricher came out years ago, in the late 80s if I recall correctly. I've got a copy of it around somewhere.
I loved that book because it did a great job integrating all the things in one place: animals, plants, habitats, evolution, etc. Even though I was working in the paleotropics at the time, I found it informative.
Then, more recently, I got a revised version of the same book. I've got it around somewhere. It is from the 1990s, I think. Great book, same idea as the first one, but with more in it, and a somewhat larger format. This dates to after my fieldwork in the rainforests, but overlapped with visits to arid regions in the tropics, though again, I'm paleo and the book is neo, but still great.
This is a serious book. To a large extent, the intended audience is folks who plan to travel in the neotropics and want a strong background in areas of evolutionary biology and conservation. But the book is very high level in terms of the material covered, the range of facts and scope of theoretical work brought to bear, and so on. It is easy to read, even engaging to read, but it is very very rich in content.
So, the book includes information on traveling, and seeing nature on your trip. But then it includes all that information on the nature itself. It is not a small book, not a field guide format (as the first version was), but it is worth lugging around if you are doing some serious visiting.
And, it should be in school libraries, and on the shelves of biology teachers. There are many well developed examples of wildlife and evolution in here, that can be expand on with further literature review (and the book provides a handle on that) for developing in class projects.
I've put the table of contents below. As you can see, the book is well organized and covers a lot of material. Also, it is a well produced (as is typical for this publisher, Princeton) and nice looking.
The author, John Kricher, is a biology professor at Wheaton. He's also written: Galápagos: A Natural History, Tropical Ecology, A Field Guide to California and Pacific Northwest Forests (Peterson Field Guides), By John Kricher - The Balance of Nature: Ecology's Enduring Myth, and a couple of book on tape thingies such as Ecological Planet - An Introduction to Earth's Major Ecosystems: The Modern Scholar (well, not really tape, of course).
